The best behaved dog I ever had was a curr mix named George. He was basically very lazy but loving. I had him for years when he showed up at my house with rope marks on his neck, heart worms and way underweight. He was very protective of his family. I had him for years, until he snuck out one morning and followed the kids to the bus and ended up hit by a car. His bad habits was he was a pillow hog, with bad breath and farted in his sleep!! So, he was in some ways like my exhusband, but in all other ways 1000 times better!!
